    Was a little iffy about performance, seeing a couple of negative reviews. Performed fine. No issues, no jams, no problem. Great value. At the range I frequent, with range membership, I get about 50% off and comes out to about $325 per 1,000 rounds. I ordered 2,000 rounds of these and paid just under $500...realizing about $100 saving.

    Good Ammo very happy with it never had a problem. The price is also not to bad I just wish that shipping was cheaper

  • Rhonda7764 said:

    The best value, fastest shipping and great ammo.

  • WWIIIHundred said:

    I normally don’t purchase steel or aluminum rounds, but it’s hard to say no when I literally can’t find or purchase any other types of ammo for my Windham Weaponry 300 BLK. I was worried that I would get a double feed or lots of jams. I honestly can say after shooting 100 rounds at the range at 100 yards; I didn’t get a single one with this ammo. My shot groups were decent too for what I consider sub par ammunition. I was honestly surprised at the results. I am definitely buying this ammo again. The best part is the ammo came to me instead of having to fight long lines hoping that there will still be ammo left on the shelf when it is my turn to grab some.

  • Savage300 said:

    I normally don't buy steel or aluminum case ammunition but due to availability at this time I decided to give it a try. I was pleased to not have a single issue during target practice. I didn't spend time worrying about grouping but all 200 rounds I used worked flawlessly. Will definitely order more.

    This is my second purchase of this ammo. The first purchase was 60 rounds. I had a great time zeroing and shoot the rifle suppressed. This ammo out performed my expectations. This purchase was 200 rounds for $342.00 including shipping. So $1.60 delivered to the front door was worth it to me. Happy shooting.

  • RazorUSMC said:

    Bought this ammo for a Run N Gun competition, it worked falsely as it should. I reload my own but with the short notice of this shoot I did not have the time to reload my own. I have some to trust Hornady products as I use there Lock N Load AP Ammo plant press. This ammo was great and was super quiet with my 10.5" SBR I will be getting some more soon so I have the brass to save this time.
